IMPROVEMENT IN SKEINS AND BOXES FOR VEHlCLE-WHEEL$.

Specification forming part of Letters Patent No. 142,233, dated August26, 1873; application filed May 10,1872.

To all whom it may concern:

Be it known that I, NATHAN L. HoLMEs, of Fond du Lac, in the county ofFond du Lac and State of Wisconsin, have invented certain new and usefulImprovements in Thimble Skeins and Boxes for Axles and Hubs; and I dohereby declare that the following is a full, clear, and exactdescription thereof, suiflcient to enablethose skilled in the art towhich my invention appertains to make and use the same, reference beinghad to the accompanying drawing, in which- Figure 1 represents the endof an axle provided with my improved skein and box. Fig. 2 is a centralvertical longitudinal section of the same. Figs. 3 and 4 arelongitudinal sections of the box and sand-band. Fig.5 is a transversesection taken in line m 00.

My invention relates to certain improvements in the thimble skein whichsurrounds the axle, and the box which lines the hub, and in theirconnection and co-operation with each other, as hereinafter describedand claimed.

The end of the axleis made in the usual tapering form. The skein B is ofcorresponding form on the inside, so as to fit the axle. On the outsideof the skein, instead of a continuous tapering bearing for the entirelength, as in the ordinary method, the bearingsurfaces are located ateach end .of the skein, as

shown at b "b, and are bounded by horizontal parallel lines, so thattheir form is cylindrical instead of tapering. The width of thesecylindrical bearings may vary according to the size and weight of thevehicle. By this construction much friction is avoided, and the draft ofthe vehicle is reduced. The sandband C is formed with an outer flange, 0

which bears against the inner end of the hub,

and an inner flange, 0 which occupies a position between a circularprojection, b, on the skein B and an annular shoulder, 01 on the box D,fitting snugly, so as to allow the parts to revolve freely, and at thesame time prevent the admission of dirt or sand to the bearings, andalso prevent grease or oil from coming in contact with the inner end ofthe hub.

The box D has horizontal or cylindrical bearings d d formed on theinside, corresponding with those on the skein, and between them, in thetapering portion, is a shallow recess,

01 which serves as a chamber or receptacle for sufficient oil to keepthe axle skein and box properly lubricated. On the inner end is theannular shoulder 61 which engages with the sand band, and on the outerend is a flange, cl, which fits into an annular shoulder, b formed onthe outer end of the skein B, said flange being thicker than the depthof the shoulder, so that a portion of it extends beyond the extreme endof the skein and forms a second shoulder, b Between the extreme end ofthe skein and box and the inner side of the nut E is a rubber or.leather packing, P, which fits closely around the screw-thread on theaxle, and is clamped tightly between the nut E and the extreme end ofthe skein B resting against the shoulder b ner side of the nut E is aflange, c, which fits over a shoulder, (F, in the end of the box D.

By means of this construction of the skein and box and the flange c onthe nut c, with the packing P interposed, when the parts are in placethey form a tight joint, preventing 'the admission of dirt or sand andthe escape of oil or grease.

The oiling device consists of a cup, F, inserted in the upper side ofthe skein over an orifice, f, from which proceeds a tube, f leading tothe bearing-surface b. The cover of the cup is held in place by a flatspring, 8, attached to the skein by a screw or rivet. By this means thebox and skein can be oiled without the necessity of removing the wheel.

box D ribs or corrugations g are formed, to engage with correspondingribs and depressions on the inside of the hub, whereby it is held firmlyand securely in place.

What I claim as new, and desire to secure by Letters Patent, is-

d, inclined or conical recess 6?, and shoulder d in combination with aspindle, B, having corresponding bearings and recess, and lubricatingreservoir and channel, and a band, 0, having flange 0 substantially asspecified. N. L. HOLMES.
